Description
BACKGROUND

1. Field of the Invention

The present invention relates generally to fueling systems for hydraulic fracturing equipment, and more specifically to a system and method for automatically fueling equipment and reporting important information in a real time for fracing hydrocarbon wells.

2. Description of Related Art

Fracturing of hydrocarbon wells requires great amounts of pressure. Diesel, natural gas, and or a combination of those driven pumps are utilized in order to generate pressures sufficient to fracture shale deposits. This equipment is located remotely and require refueling several times during a frac job. Conventional systems for fueling hydraulic fracturing equipment use trucks and pump fuel into saddle tanks from the trucks as required to keep the saddle tanks full. Alternative conventional systems bypass the saddle tanks of the hydraulic fracturing equipment and provide a pressurized fuel line and return line for each piece of equipment. Conventionally data is monitored on a per site basis typically relayed from the single sale pump to a user, therefore no one knows how much fuel each piece of equipment is using in relation to the rest of the fleet. Conventional systems and methods for fueling hydraulic fracturing equipment have disadvantages. First, stopping the frac to refill saddle tanks cost time and money. Second, different frac pump engines require different fuel pressures to operate, and keeping over a dozen pieces of equipment operating at different pressures is difficult. Third, the space at a fracturing site is limited and conventional systems require multiple hoses snaked in and around the pumps and various trailers. Thus, there exists significant room for improvement in the art for overcoming these and other shortcomings of conventional systems and methods for automatically fueling hydraulic fracturing equipment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Illustrative embodiments of the system and method for automatic fueling of hydraulic fracturing equipment with the ability to report fuel tank status, usage, and fill level are provided below. It will of course be appreciated that in the development of any actual embodiment, numerous implementation-specific decisions will be made to achieve the developer's specific goals, such as compliance with assembly-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

Automatic frac pump and frac equipment fueling provides fuel to saddle tanks of hydraulic fracturing equipment as needed by the saddle tanks. The system for automatically fueling hydraulic fracturing equipment is comprised of a fuel input system, a fuel output system, and a control system for regulating the flow of fuel from the input system to the output system. Preferably the system is compact to reduce the footprint at fracturing sites. This system comes with the ability to report fuel tank status, usage, and fill level to users at the fracturing site and remote to the fracturing site, for example at the headquarters of the exploration company.

Referring now to FIGS. 1-5 in the drawings, a preferred embodiment of mobile fueling platform for automatically providing fuel to a saddle tank of the frac equipment according to the present application is illustrated. System 101 is comprised of a fuel cap system 103, a fuel input system 105, a plurality of fuel output systems 107, and a control system 109. Fuel input system 105 is preferably comprised of an input fuel hose located on a hydraulically driven reel and is automatically retractable. As the user pulls the hose from the reel a spring is biased to provide the force to retract the input hose when needed. Alternatively, fuel input system 105 is comprised of a manifold on the platform wherein a fuel line is coupled to manifold. Fuel output system 107 is comprised of fuel hose 111, a reel 113, a remote actuated valve 115, a flow meter 117, and a ball valve 119. Reel 113 is retractable like reel from the input fuel system but is manually driven and is configured to contain the fuel hose when the system does not require a long fuel hose and for when the system is unused. Adjacent the fuel hose 111 is electrical wiring from electrical conduit 110 connecting the control system 109 to the fuel cap system 103 located on the saddle tank 121. To facilitate the clarity of the illustrations the hosing between the reels 113 and the remote actuated valves 115 has been removed, however it should be apparent that the valves 115 are coupled to the reels 113. The preferred embodiment of the reel 113 is a manual reel however due to the weight of some fuel lines a hydraulically driven reel is contemplated by this application. Flow meter 117 is configured to allow the system to report the fill status of the corresponding tank and the fuel tank usage over a stage level, a daily level, and a job level.

Fuel cap system 103 is comprised of a fuel cap 125 with a male fluid coupling, a high sensor 127, and a low sensor 129. Male fluid coupling is configured to quickly allow the fuel hose 111 connect to the fuel cap system. Each saddle tank will utilize the fuel cap system 103. The high sensor 127 of the fuel cap system is configured to measure the amount of fuel in the saddle tank near the rated capacity of the tank. The low sensor 129 of the fuel cap system is configured to measure the entire amount of fuel in the saddle tank. The high sensor is preferably an ultrasonic sensor suspended above an upper surface 131 of the fuel within saddle tank 121 and alerts the system once the fluid level in the tank is high enough to break an ultrasonic beam. The low sensor is preferably a pressure sensor and is submerged into the fluid. As the tank is filled the pressure increases. The high sensor is a redundant sensor to insure that the valve is closed when the fuel level in the tank approaches the tank's capacity. Low sensor 129 provides data to the system in order for the tank fill level to be reported.

System 101 further comprises a propulsion system having a combustion motor 135, a hydraulic system 137, a plurality of hydraulic motors 139 coupled to the wheels 141 of the system, and a steering system 143. Steering system 143 is preferably a set of hydraulic valves connecting the hydraulic system 137 to the plurality of hydraulic motors 139. A user stands on foldable bracket 147 and can steer and move the system by moving the steering system. Foldable bracket 147 is configured that the user is able to see over a top of the system to drive it. The propulsion system is preferably both 2 wheel drive and four wheel drive capable by toggling a valve. Since wells sites are typically muddy having a four wheel drive capable system facilitates moving the cart/platform near the hydraulic fracturing equipment. Furthermore, the unit can be moved by a remote control 149 that operates the hydraulic valves in control of the hydraulic motors 139. With the remote control 149 the user can drive the unit around the job site and steer clear of obstacles in the confined spaces around a fracturing site.

Control system 109 is preferably a programmable logic controller with a display and assesses the amount of fuel to dispense based upon the low sensor 129. Control system 109 can be calibrated by entering in the distance from a bottom of the saddle tank to the max fill line to determine the relative expected pressures when the tank is near the max fill line. Alternatively in addition to the low sensor an ultrasonic distance sensor measures the amount of fuel in the saddle tank by ultrasonically measuring a distance between the ultrasonic distance sensor and the upper surface of the volume of fuel in the saddle tank. High sensor acts as a redundant stop where the valve 115 is closed whenever the top of the fuel is close to the high sensor. High sensor prevents fuel spills when the low sensor fails. Control system 109 is electrically coupled to the high sensor and the low sensor by wiring located adjacent the hose 111. Both the hose 111 and the wiring to the high and low sensor are contained in a common conduit. In the preferred embodiment, the reel 113 is continually coupled between the valve and the hose 111 while the electrical wiring has a disconnect. Alternatively, both the fuel line and the wiring to the high and low sensors have sliprings in the reel and are continually coupled. Control system 109 is also wired to flow meter 117. Control system 109 tracks fuel flow to each tank by the amount of fuel flowing through the flow meter 117. This flow data provides users with feedback regarding how efficient the hydraulic fracturing equipment are operating. Furthermore, the control system provides manual control of the valve 115 by a series of switches for each reel. This allows a user to either prevent the remote activation, engage the remote valve, or allow the system to control the valve. Control system may further comprise an indicator tower and an emergency stop both located on the cart. While the preferred embodiment of the system uses wiring to connect the control system 109 to the sensors and valves, alternatively the control system is wirelessly connected to the sensors of the fuel cap system and the valves using wireless antenna 114.

Typically the system 101 is comprised of twelve fuel output systems 107 connected to a single fuel input system 105. This configuration allows for a single platform to fuel a dozen saddle tanks concurrently. Typically the fuel line of the fuel output system is ½″ or ¾″ diameter and the diameter of the fuel input system is 2″ diameter. In the preferred embodiment the control system is powered remotely, alternatively the system further comprises a generator or solar system to supply voltage to the control system.

Referring now also to FIG. 6 in the drawings, a preferred embodiment of display screen for automatically providing fuel to saddle tanks of hydraulic fracturing equipment according to the present application is illustrated. Control system 109 displays conditional information to a screen mounted to the platform. This allows users to glance at the platform and assess the condition of the system. Each tank is represented by a bar chart 201 scaled to the saddle tank capacity. High mark 203 displays the stop filling position of the system associated with tank 12. Once the fuel level is at the high mark the valve 115 closes to stop fuel flow into the saddle tank. Low mark 205 displays the start filling position of the system associated with tank 12. Once the fuel level is below the low mark the valve 115 opens and fuel flows into the saddle tank. Tank level 207 displays the relative position of the fuel level scaled. As an example, Tank 3 requires additional fuel to be added to the saddle tank because the fuel level is below the low mark as set by the user. Additionally indicators 209 display information such as pressure, flow, quantity, and valve position to the user. Each tank is separately controlled and monitored to allow users to customize the system based on the type of frac equipment, the type of saddle tank, the user's preferences, frac equipment issues or problems.

Referring now also to FIGS. 7 and 8 in the drawings, embodiments of mobile cart layouts for automatically providing fuel to saddle tanks of hydraulic fracturing equipment according to the present application are illustrated. A frac site for oil and gas wells are a congested place during the time of fracturing the well. A well head 301 is connected to a plurality of frac pumps 305 and blender/chemical trailers 307. To operate the various pumps and trailers require refueling of their diesel tanks. A mobile fueling platform 309 is located near the frac pumps 305. Preferably the platform is moved into position by driving it into position as described above however the platform can be pulled or forked into position.

A fuel cap system is installed into each saddle fuel tank. A hose is extended from each reel as needed and coupled to the fuel cap system. Additionally a hose is extended from the cart to the supply tank 311. Calibration of the sensors as needed is performed. The user then allows the controller to control the remote controlled valve by flipping a switch or depressing a button. The system then autonomously fills the saddle tanks from the supply tank 311. A sale meter is located between the supply tank and the cart to document the volume of fuel sold. Once the frac job is complete the process is reversed. The extended hoses are decoupled and retracted into the cart. The fuel caps are removed from the saddle tanks.

While the system as illustrated in FIG. 7 is shown with two carts or platforms 309 and one supply tank 311. An alternative embodiment combines the two platforms and the supply tank into a single trailer for providing automatic fueling to an entire well site. Additionally as shown in FIG. 8 the system can be comprised of two carts or platforms 309 and two supply tanks 311.

Referring now also to FIG. 9 in the drawings, an embodiments of a mobile cart system for automatically providing fuel to saddle tanks of frac pumps with real time fuel reporting according to the present application is illustrated. Reporting system 401 is comprised of a plurality of carts 403, a mobile fueling platform 402 having an onboard fuel supply tank 404, server 405, a cloud interface 407, and a plurality of connected reporting devices 409. Some connected reporting devices 409, having a unique interface 413, are combined into an enterprise system 415. The plurality of connected reporting devices 409 is comprised of laptops, cellular phones, smartphones, tablets, desktop computers. Enterprise system 415 is configured for providing specialized information for an end user. For example, a first enterprise system can be configured for an operating company and a second enterprise system can be configured for a drilling company. Each enterprise system utilizes a different user interface to provide specific information required by the enterprise. The carts 403 are connected to the server 405 such that data from the sensors of each cart is transmitted to the server. The connection is preferably wireless, however wired connections are contemplated by this application. Furthermore, the plurality of connected reporting devices are connected to the server 405 by a cloud network 407. Thereby a user can remotely track and monitor fuel status from several frac sites from a single place or check the other frac sites from a first frac site.

The reporting system takes the data from the sensors and provides real time tracking of fuel usage from the embedded sensors. The reporting system is also able to provide users with time histories of fuel usage such as: an amount of fuel usage over a stage of a frac; an amount of fuel usage over a day; an amount of fuel usage over a job; and an amount of fuel in the saddle tank. Additionally the reporting system can provide the amount of fuel in each of the saddle tanks and the supply tanks.
